Boost Logic Crank Dampener for Nissan GT-R

October 25th, 2010

Parts news update time – something we haven’t done enough of lately. In this installment we highlight the latest release from Boost Logic which is their Crank Dampener/Pulley for the VR38. The guys at Boost Logic had noticed a disturbing trend of irregular main bearing wear during engine teardowns in their workshop which they corroborated with other workshops around that were doing the same.

In their view, this is being caused by crankshaft resonance possibly seen once the GT-R in question is tuned and still running the OEM dampener designed for OEM power.

To solve this issue and the potential bearing problems it can cause over time they’ve released this dampener of their own which uses a larger, higher quality dampener ring than factory which is better suited to balance out the stronger resonance created by engines that produce more torque.

Features:

  • Reduces Torsional Vibration
  • SFI 18.1 Approved
  • 360 Degree Lazer Engraved Timing Marks
  • OEM Crank Pulley Diameter

They’re priced around the $999 mark and you can order one at one of Boost Logic’s distributors.

Breaking: GT-RR Tease Upcoming VR38 Crate Motor from Guess Who… ?

August 16th, 2010

What does an Aston Martin One-77 have in common with a Nissan GT-R? Not much frankly, until now if the latest teaser from GT-RR is to be believed – and I’m told it certainly is. I’m under strict instructions not to say any more than what’s in this one page teaser but I’ve heard about this website called Google that is good at searching for information about things these days…

That said, this motor is also built in partnership with the same company that builds motors for the likes of these GT-Rs below so I may as well use this excuse to spam my favorite wallpaper sized photo from my collection…

Forged Performance Announce the VR38 FP1 Short Block for Nissan GT-R

April 21st, 2010

It keeps getting more interesting in the built VR38 world with another newly announced complete, built, short block hitting the market in a big way. This time hailing from much closer to home for many of you, Marietta GA, comes the Forged Performance VR38 FP1 short block for Nissan GT-R.

The Forged Performance FP1 Shortblock strengthens the GT-R engine for maximum reliable power! We start with a BRAND NEW VR38 block casting, and all new OEM parts. The OEM rods and pistons are replaced with Pauter forged rods, and our own spec Arias Extreme Duty pistons. The block is precision CNC machined to accept a new cast iron cylinder liner. The cast iron liner allows for the long term reliability and exceptional strength when running forged pistons at very high power levels. The is the same proven strategy used in numerous 1500whp+ builds in the exotic car world. After the liners are fitted the cylinder walls are bored and honed to .0001 tolerance and the block is decked flat. The liners are purposely left .001 above the deck for headgasket seating and block expansion purposes. This block is engineered to handle 1000whp+ easily.

Specifications

  • Brand New VR38 OEM Block and Crankshaft
  • Pauter 4340 Billet Connecting Rods w/ ARP Rod Bolts
  • Forged Performance Spec Arias Extreme Duty 2618 Alloy Pistons (9:1 CR)
  • Forged Performance Spec Cylinder Liners
  • New Nissan Main, Rod and Thrust Bearings
  • Polished Crankshaft
  • Balanced Rotating Assembly
  • Assembled In-house by our Professional and Experienced Engine Builders

Way to go guys, another great and home grown product. If you’re interested in one of these you can expect to pay $12,090 plus freight including a brand new block.

If you’re supplying your own block, expect to pay less, around $8,590.

Hit up the Forged Performance website or contact them directly if you have any more questions, the guys are only too happy to help!

Gruppe-S VR38 Stroker Crank Officially a Work In Progress

February 18th, 2010

When the Hankook Dynamic AutoSport Gruppe-S Nissan GT-R drift car debuted at SEMA in 2009 we were fortunate enough to get an advanced preview from Dynamic Autosport’s Eddie Kim on what we could look for in terms of GT-R development. He mentioned that on top of the drift car’s chassis development they’d also be putting some focus on the VR38 development itself.

While they aren’t set on using the VR38 in the drift car just yet, (they’ll most likely be opting for a worked VQ engine), they’re very much going to be developing parts for it including a 4.0 – 4.3 liter stroker kit.

First up in the development of such a kit is to build a crank. That’s what’s happening right now and is expected to be completed in around a week. Pistons and rods up next we suppose and it should all slide nicely into their sleeved block. Should be an interesting competitor to the existing JUN 4.0 liter stroker kit which is quite a pricey item…

MCR Head Gasket Coming Soon for Nissan GT-R

February 17th, 2010

MCR have got their first trial head gaskets in for test fitting. They’re bolting up their own VR38 which they’ll then pressure test. If all goes well the guys are looking at releasing this pretty quickly.

When it’s released it’ll be just the second head gasket on the market behind the Cosworth item which was first seen at SEMA last year.

We’ll give you guys a heads up when we know pricing but it might be one to add to your shopping list if you’re doing engine work in the near future…

Tokyo AutoSalon 2010: JUN Camshafts TypeZero and Short Block with Liners

January 21st, 2010

Well the work-in-progress JUN 1000ps build with big cams is a great thing no doubt but not everyone is shooting for that level of ultimate power so they need a camshaft that will operate reliably with a more standard engine build. To fill that need, JUN Auto have produced this High Lift Camshaft TypeZero for the Nissan GT-R’s VR38DETT suitable for use with the standard ECU.

These camshafts feature identical duration and lift on both intake and exhaust sides which is 256 degrees duration and 10.3mm of lift. Not the 264 degrees and 10.5mm lift we heard for their big power build.

The price for these is set at a interesting 84,000 yen in Japan and about the $1,200 USD mark over in the states.

Update: You can now pick up a set for lower than our estimate, just $1150, online @ GT-RR

On the short block front, JUN Auto were also showing off their VR38 bare blocks with liners fitted. This is the kind of thing useful when you’ve spent the cash on the JUN Auto 4.0l stroker kit.

No pricing on the short blocks with liners just yet.
